 *         access_obj_without_check (obj);
 *     }
 *     foo (NM_TYPE (obj));

 *     // avoid the crash as NM_TYPE() cannot do anything then passing on the
 *     // invalid pointer.
 *
 * Example 3:
 *     static void foo (NMType *obj)
 *     {
 *         g_return_if_fail (NM_IS_TYPE (obj));
 *         access_obj_without_check (obj);

 *     foo ((NMType *) obj);

 *     static void foo (NMType *obj)
 *     {
 *         g_return_if_fail (NM_IS_TYPE (obj));
